Presidents & American foreign policy Are trends in global politics simply the result of large impersonal structural forces, or does human agency matter? For example, would America have become the dominant country in the 20th century regardless of who was president? To what extent did leaders matter, and if so, what kind of leader? Leadership theorists focus their attention on what they call transformational leaders, but were "transformational" leaders like Woodrow Wilson and Ronald Reagan really more important than "transactional" Author(s): No creator set

One issue, about which there is regular debate, concerns the use of ‘punishment’ to control children's behaviour. Behaviourism might, at first glance, appear to offer support for using punishment to reduce undesirable behaviour. For example, imagine that a father and his daughter are out shopping and the child steals a bar of chocolate and eats some of it whilst her father is distracted. He then sees her and shouts at her. In operant terms the stealing event is followed by an aversive res

As the previous section indicates, although ‘classic’ behaviourism is rare in contemporary explanations of child development, many of its guiding principles have been retained in some form or other in the field of learning difficulties. One of the advantages of behaviourism lies in its utility as a form of direct communication with children who are too young to speak, or who are otherwise difficult to communicate with about their behaviour. It resulted in decades of research, becoming the

In 1282, Edward I conquered Wales and the Statute of Rhuddlan (or Statute of Wales, 1284) established English rule. Rather than involve the assimilation of the Welsh by the English the conquest saw ‘a colonial system … established in those parts of Llywelyn's Principality which were by 1284 in the hands of the king’ (Davies, 1991, p. 166). In 1400, Owain Glyndwr led the most outstanding and successful rising in Wales against the new order and the tyranny of the English border barons, wh

For these short video extracts we have chosen to focus on two main viewpoints. Try not to look beyond the outline of the debate, for we are not expecting you to come to a conclusion about who is right and who is wrong – the issues are far too intricate for that. All you need to do is to recognise what the issues are and to be able to identify what arguments each side puts forward in support of its case.

The key skill being developed is identifying the arguments used by various individ

The rise of global factories in the 1970s owed much to the rapid improvement in transport and communications technologies which took place at that time and which made it possible to keep in touch with, and control, production processes in different parts of the world. Just as significant was the fragmentation of industrial production whereby parts of the manufacturing process could be relocated over vast distances. Sewing in garment and footwear production, for instance, was among the

It's that special day in the week again. People begin to gather, set apart by their passionate convictions and the symbols that bind them together. Some stand by and scoff but the like-minded take strength from each other and stride proudly on, indifferent to those who do not share their commitment. For those caught up since birth (the less sympathetic might say ‘indoctrinated’) by their elders' commitment and enthusiasm, this is the climax of their week.

The dynamic pricing model is one which has a number of different instantiations. Basically, such models treat the price of a product or service (primarily a product) as variable and open to negotiation.

The name-your-price instantiation of this model is where the customer of a site offers the price that he or she thinks is reasonable for a product or service. The administrator of the website will pass on this bid to the provider of the product or service who will decide whether t
